How to open closed MM Periods

T-Code: MMPI – from Tool Bar select – System – User Profile – Own Data – In parameter Tab Enter “MMPI_READ_NOTE” in parameter Field

Then, Remove assignment of Plants from Company Code (In SPRO).

Now use T-Code OMSY & Set the required Period.

Re-assign Plants to Company Code & Check whether correct period is open thru T-Code – MMRV

Now use T-code – OMWD to Assign Valuation grouping code to Valuation area because the earlier data gets deleted when assignment of Plants was removed.

Use the transaction code OMS2 then select FERT (for Finished Goods) or any required Material type & then click on the Quantity and Value update.
Select your plant or valuation area and put Tick Marks in Value update and Quantity update

Hope this helps,

      this document is technically vague and incomplete and even dangerous without all the warnings SAP gives in the various SAP notes for MMPI like Note 487381 - RMMMINIT: Protection against unintentionial execution

      " must be aware of the consequences of period closing with initialization.This note describes the possible data inconsistencies that might occur if you carry out the initialization in a productive system .... these inconsistencies can only be corrected within the remote consulting purchased separately...."

      you wrote "Enter "MMPI_READ_NOTE" in parameter Field" but did not say anything about the parameter value

      without parameter value the parameter is useless

      Never try this, opening closed period absolutely not to be tried at all unless it is extremely business critical and to be done only with support from SAP.

      Opening the closed Posting periods is not acceptable in SAP and for critical business reasons we want to open then we need to take help from SAP remote access.

      The process which is mentioned above will cause data inconsistencies, so be aware of using this.

      What a pity to see that the important thing about MMPI is described by someone else in the comments, not by the author (i.e. the SAP note 487381 must be read, and its procedure must be followed). Of course, what is in the note is copyright SAP and reserved to people with SAP license, but at least mentioning the link to the note is a must-to-have in this blog post.
